Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, as Figures 1 - 3 shown, a three-station automatic vacuuming and positioning tooling for a pressure vessel includes: a gas cylinder 100, a support frame 200, a positioning sliding plate 300, and a vacuuming assembly. The support frame 200 is arranged around the gas cylinder 100; a plurality of the positioning sliding plates 300 are arranged inside the support frame 200; a vacuuming assembly is further included. The vacuuming assembly includes that the first support frame 401 is fixedly connected to the positioning sliding plate 300 through a guide post. A rear push cylinder 402 is arranged at the bottom of the first support frame 401. A clamping block 403 is arranged at the output end of the rear push cylinder 402. A positioning bearing is arranged on the clamping block 403. The first support frame 401 is connected to a second support frame 404 through a rotating bearing, and first return springs 410 are installed between both sides of the second support frame 404 and the first support frame 401. A front push cylinder 405 is arranged at the bottom of the second support frame 404. A third support frame 407 is arranged at the output end of the front push cylinder 405. An air extraction guiding fork 406 is arranged at the output end of the third support frame 407. An air extraction head 408 is further arranged at the output end of the third support frame 407. An air valve positioning bracket 409 is further arranged at the bottom of the first support frame 401. A guiding shaft and a second return spring are installed on the air extraction guiding fork 406. The air cylinder knob is propped against by the air valve positioning bracket 409 to make the heights of the air extraction head 408 and the air valve air outlet the same. Then, the clamping block 403 is driven by the rear push cylinder 402, and the air extraction guiding fork 406 is driven by the front push cylinder 405 to make the clamping block 403 and the air extraction guiding fork 406 approach each other, so as to clamp the gas cylinder and position the gas cylinder shield and the air valve. Then, the air extraction head 408 is pushed into the air cylinder port by the front push cylinder 405 to perform a vacuuming operation on the gas cylinder.

[0027] In one embodiment, as Figure 1 and Figure 2As shown, the lifting assembly includes a first support plate 501, the first support plate 501 is arranged at the top of the support frame 200, several lifting cylinders 502 are arranged at the top of the first support plate 501, the output end of the lifting cylinder 502 is fixedly connected with a cylinder lifting plate 503, the positioning sliding plate 300 is movably connected with the cylinder lifting plate 503 through a guide shaft. By driving the cylinder lifting plate 503 with the lifting cylinder 502, the positioning sliding plate 300 is connected to move up and down together. The air valve positioning bracket 409 on the first support frame 401 limits the descending height of the positioning sliding plate 300 to ensure that the horizontal height of the air extraction head 408 is the same as that of the air valve outlet.

[0028] In one embodiment, as Figure 1 shown, the production line includes a chain baffle 601, the chain baffle 601 is arranged on the side of the steel cylinder 100, several transmission rollers 602 are arranged inside the chain baffle 601, and the transmission rollers 602 are movably abutted against the bottom of the steel cylinder 100. Through the mutual cooperation between the transmission rollers 602, the steel cylinder can move.

[0029] In one embodiment, as Figure 1 shown, the limiting assembly includes a second support plate 701, the second support plate 701 is arranged on the support frame 200, several intercepting cylinders 702 are arranged on the second support plate 701. By starting the intercepting cylinders 702, the steel cylinder is intercepted and limited, and the second support plate 701 supports the intercepting cylinders 702.

[0030] In one embodiment, as Figure 2 and Figure 3 shown, rollers are arranged on both sides of the clamping block 403, which is convenient for rotatably positioning the steel cylinder guard when clamping the steel cylinder.

[0031] The above embodiments disclose a three-station automatic vacuum pumping and positioning tooling for pressure vessels. Among them, when the machine is started, each moving part runs to the initial state. A sensor is set at the front end of the assembly line (the end of the previous assembly line can sense the position of the steel cylinder). When the sensor does not sense that a steel cylinder flows down from the previous assembly line for 1 minute, the assembly line stops rotating. When the steel cylinder flows into the first station, the interception cylinder 702 II is pushed out, the lifting cylinder 502 of station one presses down. After the cylinder of station one presses down in place, the rear push cylinder 402 and the front push cylinder 405 are pushed out. At this time, the vacuum pumping and clamping of station one are completed. When the steel cylinder flows to station two, the interception cylinder 702 III is pushed out, and the same vacuum pumping and clamping action as that of station one is performed. When the steel cylinder flows to station three, the main interception cylinder 702 is pushed out, and the same vacuum pumping and clamping action as that of station one is performed. After the vacuum pumping and clamping actions of the three stations are completed, the vacuum pumping action is started, and the three stations pump vacuum simultaneously. After the vacuum pumping is completed, the lifting cylinder 502, the front push cylinder 405, and the rear push cylinder 402 are reset. After the reset is completed, the three rear interception cylinders 702 retract to release the steel cylinders that have been vacuum pumped. When all the steel cylinder outflow signals are received, the main interception cylinder 702 retracts to release the next wave of steel cylinders for vacuum pumping, and the actions are cycled in sequence.

[0032] As described above, the above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
